Method and device for mounting a flexible bag

Abstract

This device is for maintaining a flexible bag in an open manner. It has an inner hoop having an outer side wall sloping inwardly and downwardly, and an outer binder which is provided with a through opening having a complementary shape and size adapted to embrace the outer side wall of the inner hoop. The flexible bag is mounted between the inner hoop and the outer binder by first inserting the bag through the inner hoop with the bag's lip portion folded backwards to cover over the outer side wall of the inner loop. The outer binder is then fitted over the inner hoop with the folded back lip portion of the bag sandwiched between the engaging inner hoop and the outer binder. When the bag is being filled, the weight in the bag will inherently pull the inner hoop and the outer binder to engage with each other with increasing force as the weight of the load increases, and thus, in turn, securing the bag even more tightly to the device.

What I claim is:  
     
       1. A method of holding a flexible bag is an open condition, comprising: 
       inserting said flexible bag into a hoop member having an outer side wall sloping inwardly and downwardly,  
       wrapping a lip portion of said flexible bag over said outer side wall of said hoop member,  
       placing said hoop member with said flexible bag mounted thereon into a binder member, said binder member having an inner wall surface shaped and sized to embrace said outer side wall of said hoop member whereby said lip portion of said flexible bag wrapped over said outer side wall of said hoop member is sandwiched securely between said hoop member and said binder member.  
     
     
       2. A method according to claim  1  wherein said hoop member and said binder member are annular hoops. 
     
     
       3. A method according to claim  1  wherein both of said hoop member and binder member have a top flange formed at a top edge therein and adapted to engage in contact with one another when said hoop member is located within said binder member. 
     
     
       4. A method according to claim  1  wherein said hoop member and said binder member are triangular in shape. 
     
     
       5. A method according to claim  1  wherein said binder member is a counter top having a binding opening formed therein, and said binding opening is shaped and sized to embrace said outer side wall of said hoop member. 
     
     
       6. A device for holding a flexible bag in an open condition, comprising 
       a hoop member having an outer side wall sloping inwardly and downwardly, said hoop member being operative to receive a flexible bag to be inserted therethrough with a lip portion of said bag wrapped over said outer side wall,  
       an outer binder member having inner side wall therein shaped and sized in complementary to said outer side wall of said hoop member, said hoop member and said outer binder member being engageable with one another with said outer side wall of said hoop member juxtaposed to said inner side wall of said binder member.  
     
     
       7. A device according to claim  6  wherein said hoop member and said outer binder member are annular hoops. 
     
     
       8. A device according to claim  7  wherein hoop member has a top edge with a horizontal flange formed therein, and said binder member also has a top edge with a complementary horizontal flange formed therein, said horizontal flange of said hoop member abutting said complementary horizontal flange of said binder member when said hoop member is engaged within said binder member. 
     
     
       9. A device according to claim  8  wherein said binder member includes a support portion adapted for mounting said binder member fixedly to a vertical supporting wall with said binder member extending horizontally in a cantilever manner from said vertical supporting wall. 
     
     
       10. A device according to claim  9  including a reinforcing neck portion provided between said support portion and said binder member, said neck portion adapted to maintain said binder member rigidly in said horizontal position. 
     
     
       11. A device according to claim  10  including a plurality of retainer openings formed in said outer side wall of said hoop member, each one of said retainer openings having a slit opening extending therefrom to a lower edge of said hoop member. 
     
     
       12. A device according to claim  6  wherein said hoop member and said binder member are hoops triangular in shape having two sloping sides and an extended flat side, said extended flat side being operative for supporting said hoop member and said binder member to rest on a ground surface. 
     
     
       13. A device according to claim  12  including a plurality of transverse elongated slot openings formed in each side of said binder member, and a plurality of transverse short slot openings formed in each side of said hoop member, said short slot openings of said hoop member being in registry with said elongated slot openings when said hoop member and said binder member are engaged with each other with said binder member embracing said hoop member. 
     
     
       14. A device according to claim  13  including a dimple formed in an under surface of said extended flat side of said hoop member, and a depression formed in a top surface of said extended flat side of said binder member, said dimple and said depression being operative to engage with one another when said hoop member and said binder member are engaged with one another. 
     
     
       15. A device according to claim  13  including a handle provided at a top corner between said side walls of said binder member. 
     
     
       16. A device according to claim  15  wherein the top of said sides of said hoop member and said outer binder member are slanted backwards at about 5 to 15 degrees to the vertical axis when said device is resting on the ground on said extended flat side. 
     
     
       17. A device according to claim  6  wherein said binder member is a counter top having a binding opening formed therein, said binding opening having an inner side wall shaped and sized complementary to said outer surface of said hoop member and being operative to receive said hoop member to engage therein with said outer surface of said hoop member abutting with said inner side wall of said binding opening.
